The SABMBOVP218 is a precision dual over-voltage protection printed circuit board populated with an ALD910018SALI SAB MOSFET IC, designed for balancing series-connected supercapacitors by clamping individual cell voltages at 1.80V. The board measures 0.6 inch by 1.6 inch with mounting holes and features two matched OVP circuits that provide a sharp current transition from below 1 nA at 1.70V to over 100 mA at 1.83V. It operates within an industrial temperature range of -40°C to +85°C and is RoHS compliant. The circuit provides automatic, untrimmed balancing with near-zero power dissipation below the threshold voltage and is suitable for energy harvesting and battery-powered applications.
ALD offers a line of Supercapacitor Auto Balancing Integrated Circuits (IC) as well as SAB and SABOVP (Over-Voltage Protection) Printed Circuit Boards (PCB). The SABOVP PCBs provide voltage balancing of series-connected supercapacitors through superior over-voltage clamping circuitry. These products, when used in appropriately designed applications, dissipate near-zero leakage currents, practically eliminating extra power dissipation. Supercapacitors connected in series stacks can be balanced with various combinations of multiple cascaded SABMB or SABMBOVP packages.
